Abstract
We study the structure of the \(C^*\)-algebras generated by Toeplitz operators acting on the weighted Bergman space \({\mathcal {A}}^2_{\lambda }({\mathbb {B}}^2)\) on the two-dimensional unit ball, whose symbols are invariant under the action of the group \({\mathbb {T}}\). We consider three principally different basic cases of its action \(t:\,(z_1,z_2) \mapsto (tz_1,t^{k_2}z_2)\), with \(k_2=1,0,-1\). The properties of the corresponding Toeplitz operators as well as the structure of the \(C^*\)-algebra generated by them turn out to be drastically different for these three cases.
